IC card memory having a specific recording format and method for recording/reproducing a digital voice therefrom

Abstract

An IC card memory includes a header region for storing information about the IC card memory and information about a format, a chapter attribute table (CAT) region for storing information relating to a single chapter, a cluster index table (CIT) region for storing an address of a single cluster index corresponding to a recorded data block, and a data region for storing digital voice data.

What is claimed is: 
     
       1. An IC card memory which receives and stores input information, comprising: a header region for storing IC card memory information regarding the IC card memory and format information regarding a format in which the input information is stored;   a chapter attribute table (CAT) region for storing chapter information related to a chapter, wherein a chapter corresponds to the input information stored in the IC card memory during execution of an operation, the chapter information including information for identifying a starting cluster index table corresponding to the input information;   a cluster index table (CIT) region for storing one or more cluster index tables including the starting cluster index table, wherein the starting cluster index table includes an address corresponding to a data block recorded in the IC card memory; and   a data region for storing the input information in said data block.   
     
     
       2. The IC card memory as claimed in claim 1, further comprising a spare region for storing data relating to an occurrence of a bad-block in one of said header, CAT, CIT, and data regions; wherein said bad-block is a portion of said regions having an error. 
     
     
       3. The IC card memory as claimed in claim 1, further comprising a bad-block managing region for storing information for managing a bad-block generated in said data region, wherein said bad-block is a data block having an error. 
     
     
       4. The IC card memory as claimed in claim 2, further comprising a bad-block managing region for storing information for managing said bad-block generated in said data region. 
     
     
       5. The IC card memory as claimed in claim 1, wherein a start address of said CIT region is stored in the least significant bits of said CAT region. 
     
     
       6. The IC card memory as claimed in claim 2, wherein a start address of said CIT region is stored in the least significant bits of said CAT region. 
     
     
       7. The IC card memory as claimed in claim 5, wherein said start address of said CIT region designates a cluster index address of said CIT region, and wherein said designated cluster index address designates another cluster index address. 
     
     
       8. The IC card memory as claimed in claim 7, wherein said input information is digital voice data. 
     
     
       9. A method for recording and reproducing an input signal using an IC card memory and a recording/reproducing apparatus, comprising the steps of: sensing whether the IC card memory is inserted in the recording/reproducing apparatus;   reading a check array stored in a bad-block managing region of the IC card memory and determining if said check array is correct;   determining if a spare region of the IC card memory has recorded contents and if so reading said contents and an address from said check array and reading a header region of said IC card memory; and   loading a chapter attribute table and a chapter index table if said header information is correct.   
     
     
       10. The method for recording and reproducing an input signal as claimed in claim 9, further comprising the step of: repeatedly reading blocks of a spare region of the IC card memory until one of the read blocks is determined to correspond to said bad-block managing region if said check array of said bad-block managing region is determined to be incorrect.   
     
     
       11. The method for recording and reproducing an input signal as claimed in claim 10, wherein said input signal is a digital voice signal.
